1 Claim.

This invention relates to improvements in a flask pin and cope guide, its primary object being to provide a flask pin, ear and cope guide, having brace means thereon providing purchase on the cope and drag which will prevent either rocking or shifting of the cope While it is being withdrawn from the drag.

A further object of the invention is to provide a sliding guide for the pin with adjustable means thereon to assist in the assembling or dissembling of the flask.

With these and other objects in View that may appear while the description proceeds, the invention consists in the novel construction and arrangement of parts as hereinafter more specifically set forth, claimed and shown in the accompanying drawings forming part of this present application and in which?- Fig. l is a front elevation of my invention as assembled on a flask.

Fig. 2 is a side elevation of the same.

Fig. 3 is an end View of the pin.

Fig. 4 is a longitudinal sectional View disclosing more clearly the adjusting means.

Fig. 5 is an elevation of the cope guide with the adjustable member removed.

Fig. 6 is an elevation of the adjustable member of the cope guide.

Referring more in detail to the drawings in which similar reference characters designate corresponding parts throughout the several views, it will be seen the invention consists of a flask pin 10, constructed integral with a base member 11. The said pin is a relatively long V shaped member having its upper end strengthened by a transverse web 12 and the corners 13 beveled to assist the pin entering the guide. The said base member 11 is provided with brace lugs 14 which are at right angles thereto and are to brace the pin and base member when secured to the drag 15, screw apertures and screws 16 being placed in the base member for this purpose. Two outwardly extending lugs 17 are likewise provided on the base member to assist manipulation of the drag and cope members when the same are being separated.

The cope guide consists of a main base member 18 having brace lugs 19 to match with the lugs 14 on the pin base. Screw apertures and screws 20 are likewise provided whereby the guide may be secured to the cope 21. On the main base member 18 is a right angled projecting member 22 having suitable brace webs 23 to strengthen the same, forming the guide support. The guide 24 is formed substantiallly of V shaped section having a right angled member 25 constructed integral therewith. The said member 25 is provided with apertures 26 whereby the member is secured to the guide support 22; elongated apertures 27 being provided in the guide support for that purpose. The guide 24 has a finished inner face to engage the outer face of the pin 10 which is also nished.

The guide is made adjustable by means of the said elongated apertures 27 provided for screws 28. Provision is also made for fine adjustment of the guide. This consists of a boss 29 on the guide support having a threaded aperture therein. A set screwv 30 having a check nut 31 is threadably engaged in the said aperture and extends from the bottom of the boss to engage the guide 24. In operation the screws 28 may be slightly loosened and the set screw 30 tightened on the guide until the same has sufficient tension on the pin 10. The check nut 31 is then tightened, also the screws 28 which positively keeps the guide in correct relationship with the pin and permits the cope being removed from the drag and replaced thereon without any play whatsoever.

It is believed that the design, construction and advantages of the invention will be apparent from the foregoing paragraphs taken in conjunction with the accompanying drawings without further detailed description.

While the preferred embodiment of the invention has been disclosed, it is understood that minor changes in the details of construction, combination and arrangement of co-operating parts may be resorted to within the scope of what is claimed without departing from the spirit of the invention.

I claim:

1n a device of the character described, a drag base plate secured to the outer face of the drag and having brace lugs extending at right angles over the upper edge of the drag, a V-shaped flask pin formed integral with said drag base plate and extending upwardly therefrom, a cope base plate secured to the outer face of the cope having brace lugs extending over the edge of the cope in confronting relation to the brace lugs of said drag base plate, a guide supporting plate extending at right angles to said cope base plate having an opening therethrough to receive said ask pin, a V-shaped guide disposed in the opening of said guide supporting plate in engaging relation to said flask pin, an extension disposed at right angles to said guide above said supporting plate, adjusting screws extending through said extension and elongated slots in said supporting plate for clamping said guide in its adjusted position, a boss formed integral with the bottom of said supporting plate, and a set screw threaded through said boss for engagement with said guide whereby the guide may be adjusted with respect to said flask pin.

HERMAN CHARLES MITCHELL.
